QUESTION: 1

### A hydraulic coupling

Solution:

The hydraulic coupling is the simplest means of transmitting torque' hydraulically, it can be defined as a device in which a fluid, usually oil transmits torque from one shaft to another, producing an equal torque in the other shaft.

QUESTION: 2

Solution:
QUESTION: 3

### Consider the following statements pertaining to fluid coupling: 1. Low viscosity fluids are preferred. 2. Increasing the density of fluid increases torque transmission at a given speed. 3. Fluid coupling are widely used in Automobiles, Aviation and Marine machinery. Which of the above statements are valid?

Solution:
QUESTION: 4

Which of the following parts act as a reaction member and positioned in the middle of flow from the impeller and the runner in a torque converter

Solution:

A torque converter consists of
(i) pump impeller connected machanicaliy to the driving shaft.
(ii) turbine runner connected to the driven shaft.
(iii) stator usually known as reaction member, positioned in the middle of the flow from the impeller and the runner. The stator has guide vanes which change the direction to the liquid impinging on the runner and thus causes the torque delivered to the driven shaft to be higher than that of driving shaft.
